- Plot: Benito Balducci, a lonely door-to-door toilet detergent salesman, finds himself dominated by two powerful obsessions: loving his body and loving to have sex. With this in mind, Benito, who shamelessly and openly embraces his vices, is also a meticulous diary keeper of his intense erotic fantasies, partially triggered by Luigia--his insatiable girlfriend who always tries to make him jealous--and Rome's beautiful women. Indeed, blondes or brunettes, they all provoke his wild appetite and imagination. But pretty soon, Benito will have to decide: it's either them or Luigia.
